SODA AND MENTOS Physical Science (3rd block) Mythbusters Project Introduction This experiment is to prove the theory that when Mentos is dropped into a bottle of soda the end result is a huge fountain spray of soda from the bottle due to a process called nucleation. Hypothesis If I drop Mentos candy into a bottle of soda‚ then it will create a huge fountain splash. Materials *Regular Mentos Candy (one)

Soft drinks‚ also called as sodas‚ are one of the most popular beverages that are drunk worldwide. Several brands of sodas‚ mainly from the brands The Coca-Cola Company‚ Pepsi‚ and Dr. Pepper-Snapple‚ are competing in their sales. As of 2012‚ the leading brand of food beverages is Coca-Cola. Statistics show that more than a billion Coca-Cola products are consumed daily worldwide. That means that we are consuming more sodas than ever before‚ and many health issues are showing up‚ including teeth problems

Experiment ANALYSIS OF SODA ASH The CCLI Initiative Computers in Chemistry Laboratory Instruction LEARNING OBJECTIVES The objectives of this experiment are to . . . • understand the titration curve for a diprotic base. • use the titration curve to calculate the percent of Na2 CO3 in an unknown sample of soda ash. BACKGROUND Sodium carbonate is an important industrial chemical. It is used in the manufacture of soap‚ glass‚ paper and as a source of alkalinity‚ that is‚ as a

November 30‚ 2012 Soda Pop More and more young people are experiencing hypertension and childhood obesity‚ and because of which are seemingly becoming more prone to various diseases (Should Government Tax Sugary Drinks?). Many take a stand on the issue‚ as New York for example no longer allows the use of trans fats in their restaurants. Still the cost of unhealthy food has remained nearly the same‚ while the cost of a high yield diet has soared beyond that of the rate of inflation (Should Government

Experiment # 4: Analysis of Soda Ash Experiment # 5: Volumetric Analysis of a Carbonate – Bicarbonate Mixture Submitted by: Eugenio December 2012 Department of Chemical Engineering University of Santo Tomas España‚ Manila Abstract Soda ash is the common name for sodium carbonate (NaCO3)‚ a chemical salt derived from carbonic acid. It is frequently used in manufacturing‚ industry‚ and in domestic chores. Glass production is one of the primary industrial uses for sodium carbonate. It is also

Microscale Crystallization – Craig Tube For this experiment‚ we had to find the percent recovery and melting point of pure sulfanilamide from impure sulfanilamide using the crystallization technique. To start‚ .1004 grams of impure sulfanilamide was put into a Craig tube with enough ethyl alcohol to barely pass the top of the sulfanilamide. The Craig tube was put into a stone block until boil‚ then check to see if the solid material had dissolve. With the addition of two more drops from a supply
